This package is trying to implement RFC-compatible SMTP server fo go.
swaksto test our SMTP server
See
examples/.
Save this code to example.go(same code could be found in examples/logging-smtpd/main.go):
package main
import (
"io/ioutil"
"net"
"time"
"github.com/Sirupsen/logrus"
"github.com/davecgh/go-spew/spew"
"github.com/corpix/smtpd"
)
type smtpServer struct{}
func (s *smtpServer) ServeSMTP(c net.Conn, e *smtpd.Envelope) {
logrus.Infof(
"Received message from %s those envelope: %s\n",
c.RemoteAddr(),
spew.Sdump(e),
)
msg, err := e.Message()
if err != nil {
panic(err)
}
body, err := ioutil.ReadAll(msg.Body)
if err != nil {
panic(err)
}
logrus.Infof("Message body: %s\n", body)
}
func main() {
var err error
c, err := net.Listen("tcp", "127.0.0.1:2525")
if err != nil {
panic(err)
}
for {
err = smtpd.Serve(c, &smtpServer{})
if err != nil {
logrus.Error(err)
time.Sleep(1 * time.Second)
}
}
}And run the server:
go run example.goIt will listen on 127.0.0.1:2525.
swaks -f [email protected] -t [email protected] --server 127.0.0.1:2525You should see output similar to this:
# remote 127.0.0.1:55912 at 2017-02-16 15:42:56 +0000
